Abstract
In this comment, we falsify the reasoning, given in a recent paper, that it is possible to certify entanglement by acting only on one of the parts of an entangled system. We stress that by assuming the possibility of detecting nonlocality in this way, we dispose of causality by allowing superluminal communication.
